Having problems with mine too on my new Hisense TV. Two HDMI ports will input 120fps just fine, but won’t accept an audio or HDR signal from the deck…? if i use one of the “normal” HDMI ports (not listed for gaming) HDR enables just fine but i’m limited to 4k60 with zero option for higher refresh rates even at lower resolutions.
What’s odd is that my macbook outputs HDR on any port, and 120hz, even on the “60hz” HDMI ports. idk what’s up but it might be a bad implementation on Valve’s end and not the TVs themselves.
i started the blind forest on my LCD last week just to see how much even an SDR 2D game would benefit from OLED and it’s unbelievable how night and day it is.
Another game that looks great that runs at nearly 90fps on high with HDR is Forza Horizon 4, been playing it like crazy and the skybox looks insane in HDR, i’ve never seen clouds pop out the neon white they are in real life except in maybe some iPhone HDR videos, really mind blowing.
